iOS 中的 UILocalNotification 中不显示操作和类别 [英] actions and categories don't show in UILocalNotification in iOS

问题描述

我从苹果文档中获得以下内容 这里是我需要的UILocalNotification类别:

I have the following which I believe from the apple documentation here is all I need to have a category for UILocalNotification:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {


    UIMutableUserNotificationAction *acceptAction =
    [[UIMutableUserNotificationAction alloc] init];

    // Define an ID string to be passed back to your app when you handle the action
    acceptAction.identifier = @"ACCEPT_IDENTIFIER";

    // Localized string displayed in the action button
    acceptAction.title = @"Accept";

    // If you need to show UI, choose foreground
    acceptAction.activationMode = UIUserNotificationActivationModeBackground;

    // Destructive actions display in red
    acceptAction.destructive = NO;

    // Set whether the action requires the user to authenticate
    acceptAction.authenticationRequired = NO;


    // First create the category
    UIMutableUserNotificationCategory *inviteCategory =
    [[UIMutableUserNotificationCategory alloc] init];

    // Identifier to include in your push payload and local notification
    inviteCategory.identifier = @"INVITE_CATEGORY";

    // Add the actions to the category and set the action context
    [inviteCategory setActions:@[acceptAction]
                    forContext:UIUserNotificationActionContextDefault];

    // Set the actions to present in a minimal context
    [inviteCategory setActions:@[acceptAction]
                    forContext:UIUserNotificationActionContextMinimal];

    NSSet *categories = [NSSet setWithObjects:inviteCategory, nil];



    UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:categories];
    [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];

    // Handle launching from a notification
    UILocalNotification *localNotif =
    [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
    if (localNotif) {
        NSLog(@"Recieved Notification %@",localNotif);
    }

    return YES;
}

以下是我构建本地通知的方法:

Here is how I construct my local notification:

NSDate *dateChosen = [self.reminderDatePicker date];
    NSCalendar *calendar = [NSCalendar currentCalendar];
    NSDateComponents *components = [calendar components:(NSCalendarUnitHour | NSCalendarUnitMinute) fromDate:dateChosen];
    NSInteger hour = [components hour];
    NSInteger minute = [components minute];

//    NSCalendar *calendar = [NSCalendar currentCalendar];
//    NSDateComponents *components = [[NSDateComponents alloc] init];
    [components setDay: 3];
    [components setMonth: 7];
    [components setYear: 2012];
    [components setHour: hour];
    [components setMinute: minute];
    [components setSecond: 0];
    [calendar setTimeZone: [NSTimeZone defaultTimeZone]];
    NSDate *dateToFire = [calendar dateFromComponents:components];



    UILocalNotification *localNotification = [[UILocalNotification alloc] init];
            localNotification.fireDate = dateToFire;

            [localNotification setRepeatInterval: kCFCalendarUnitDay];
            NSLog(@"Notification will be shown on: %@ ",localNotification.fireDate);
            localNotification.userInfo = [[NSDictionary alloc] initWithObjectsAndKeys:self.dayPeriod, @"name", nil];
            localNotification.timeZone = [NSTimeZone defaultTimeZone];
            localNotification.alertBody = alertMessage;
            localNotification.alertAction = NSLocalizedString(@"View details", nil);
            localNotification.repeatInterval = NSDayCalendarUnit;
            localNotification.soundName = UILocalNotificationDefaultSoundName;
            localNotification.applicationIconBadgeNumber = -1;

            [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

它只显示带有关闭按钮的默认通知，而不是我的接受按钮.

It just shows the default notification with a dismiss button and not my accept button.

如何让这个接受"按钮显示在我的本地通知上?

How can I get this "accept" button to show on my local notification?

推荐答案

您在 UILocalNotification 的主体代码中缺少的一件事是明确告诉它是基于类别的通知.

The one thing that your missing in your main body of code for UILocalNotification is explicitly telling it to be a category based notification.

将类别属性添加到您的通知中:

Add the category property to your notification:

localNotification.category = @"INVITE_CATEGORY";
